GREEN BAY — The Packers placed six players on the physically unable to perform (PUP) list as training camp opened on Tuesday morning, including WR Jordy Nelson and TE Jared Cook, but Head Coach Mike McCarthy is not overly concerned with any of their injury situations.

The other players not practicing at the start of camp are WR Ty Montgomery, G T.J. Lang, C Corey Linsley and LB Sam Barrington.

McCarthy said that based on his conversations with team physician Dr. Pat McKenzie, none of the injury issues involving the six players is a long-term concern. He did not give a timeline on any players.

“I’m not concerned,” McCarthy said prior to Tuesday morning’s practice. “I think all six of those guys will come back at some point in training camp.”

Cook is the newest Packers player among the six, and he missed the tail end of the offseason program due to his foot injury, but McCarthy doesn’t believe it will take him long to get back up to speed once he returns to the field.

As for RB Eddie Lacy, “Eddie’s ready,” McCarthy said. “Frankly, I’m done talking about people’s weight … we all have things to work on, and Eddie’s ready to go.”

The Packers are beginning camp a few days earlier than usual because they are playing in the Hall of Fame Game on Aug. 7, a fifth preseason game. McCarthy said that he’ll handle the veteran players appropriately with the longer camp and preseason, but the extended time is good for the young players.

“It helps the evaluation process. I like the extra practice time,” he said. “We’re a young football team, so we can’t have enough time. It’s something we’ll benefit from.”
